How are covalent compounds named?
Covalent compounds are molecules formed by non-metals bonded together by sharing electrons.
Covalent compounds are named by using numerical prefixes to identify the number of atoms in the molecule.
For example Carbon Dioxide
Carbon Dioxide has one carbon atom and two oxygen atoms as identified by the prefix di = 2. Carbon Monoxide has one carbon and one oxygen as identified by the prefix mono = 1.
The numeric prefixes are
mono = 1
di = 2
tri = 3
tetra = 4
penta = 5
hexa = 6
hepta = 7
octa = 8
nona = 9
deca = 10
In the naming, never use mono- for the first element.
The first element keeps its name.
The second element always end in the suffix -ide.
Drop the double vowel for the prefix and the element of the second element in the compound.
